This invention relates to agricultural and other types of machines, implements and the like embodying one or more spring-tine carrying members functionally arranged in any desired manner of which but one example is the reel assembly of i a side delivery rake.

In prior constructions, a practical mounting of spring-tine elements on reel bars and the like has heretofore been generally such as to necessitate removing the bar from the reel or other support therefor in order to replace those tine elements which have worn out or become broken, Consequently, with the practical constructions heretofore known replacement of the tine elements requires considerable time and effort, is at times difficult, and in all cases the structure being serviced must remain idle for an objectionable length of time.

It is therefore the object of this inventionto provide an f improved, practical spring-tine mounting for reel bars and other members which permits the tine elementsto be severally, readily secured to and removed from the support therefor with a minimum of time and effort, which affords an effective support for' the coil portion or portions of the tine element during both tedding and raking operations, and'which affords a simplied, durable and inexpensive construction.

The construction of a spring-tine mounting in accordance with this invention will become readily apparent as the disclosure progresses and particularly points out characterizing features considered of special importance and of general application.

Accordingly, the invention may be considered as consisting of the various details of construction, combinations of elements and arrangements of parts as is more fully set forth in the appended claims and in the detailed description, reference being had to the accompanying drawing, in which:

Fig. 1 is a partial front elevation of a rake reel bar embodying the invention;

Fig; 2 isa view taken on line II-II of Fig. 1;

Fig. 3 is a top plan view of the structure shown in Fig. 1;

Fig. 4 is a plan view of the tine loop engaging washer element; and

Fig. 5 isa side elevation of the washer element shown in Fig. 4.

Referring to the drawing, it is seen that the invention may beappliedto a tubular reel bar member or the like land to dual toothed springtine `elements including a pair of spaced opposed coil portions 2,A a toothportion S'extending; ,from

5 claims. (ol. 56-400) 2 the outer side of each coil portion, and a loop portion 4 uniting the coil portions 2 and extending away therefrom preferably in an opposite direction with respect to tooth portions 3; the outer extremity or mid-section of'loop portion 4 being preferably bent or otherwise shaped to en'- gage the top side of tubular member I with coil portions 2 disposed in spaced adjacent parallel relation with respect to the opposite or underside of member I as is best indicated in Figs. land Member I is provided with a series of longitudinally spaced pairs of alined holes or bolt receiving bores l and the spring-tine elements are readily detachably secured to member I by means of a part 'I having oppositely extending end portions 8 supportingly disposed within coil portions 2 and an offset, apertured intermediate portion 9 adapted to engage the underside of member I with the aperture therein alined with a pair of bolt receiving bores 6 and by a carriage bolt part or element II having a head portion I2 engaged by loop portion 4 as is best indicated in Fig, 3 with its opposite or nut engaging end projecting through the aperture in the offset portion 9 of part' 1? Y The head portion of part I I is preferably providedwith a removable. washer element or the like I3 shaped to nonrotatably engage and retain loop portion 4 in firm engagement with the upper side of member I and the offset portion 9 of part 'I is preferably shaped to present an upper' surface complementary to the underside of lmember I as is best shown in Fig. 2. Likewise, the end portions 8 of part 'I are preferably shaped to conform with the inner peripheral surface of coil portions 2. In this connection, it should be particularly noted (see Fig. 2) that the combined height of the end and offset portions of part 1 is less than the inner diameter of coil portions 2 thereby permitting part 1 to be inserted'and withdrawn through either coil portion to and from a position in which its offset portion '9 is disposed between coil portions 2 with its end portions 8 supporting same. 1

In assembling the spring-tine element on a reel bar member or the like, the element maybe positioned against member-I with loop portion 4 surrounding a bore 6 therein whereupon parts 'I,

, I3 and I I may then be assembled in the order vsa named, or if desired, part 'I may be rst inserted` through a coil portion 2, that` is, before the spring-tine element is positioned on member' I In either case, all that has to be done after in- .Y sertion of part II in order to detachably securely unite the various parts in they relation shown is to apply a nut I4 to the lower exposed end of part I I and tighten same thereon which can be readily accomplished since, as best shown in Figs. 4 and 5, Washer I3 is provided with offset portions I6 and I'I which prevent a turning of the Washer relative to loop portion 4 and with a square bolt hole I8 which in turn prevents rotation of the carriageV bolti part IIf when the nut is: tightened thereon. Obviously, Whether the loopor fastening portion of the spring-tine element and the parts 'I and I I are shaped to engage diametrically opposed exterior surface portions of` a. tubular member or merely different and preferably spaced surface portions or` sides; of. a: tubular.' on other shaped member is a matter-'ot selection and may be varied as desired.

This type of mounting aiords. all ot the ad` vantages with respect to strength and durability present in prior constructions in which. a reel bar member or the like. passes through and suitably supports. the.4 coil portion or portionsv of the spring-tine element mountedthereonduring both redding. and raking., operations, and ini. addition, affords a. greater deg-ree. of iiexingor spring action and permits the time.v elements to. be; severally secured. to and. removed. from. the. supporting member. with. aA minimum oftime. and effort.

The, invention is' applicable toI various types of springe-tine supportedelements and although certain correlations of. features. are peculiar to spring-tine elements including spaced. opposed coil portions. and a. uniting loopfportion, other. features: are of more general application, and it should thereforebe understood. that itis not desired. to. limit the invention to the exact details of-.construction.and. correlationsot featuresherein shown and described. forv purposes of. illustration as. various modifications Within the scope.V of the appended claims. may occur to persons. skilled in the art..
